Simplicity and Explanation in Metrical Typology Eugene Buckley University of Pennsylvania NAPhC4 — 13 May 2006 1

Theoretical Desiderata • Descriptive adequacy – can every language be generated? • Formal simplicity – are constraints evaluated locally? • Typological accuracy – are unattested languages impossible? – what is the right locus of explanation? 2

Trends in Metrical Typology • Directional foot construction. – stepwise iteration • Gradient alignment in OT. – modeling of the iterative approach • Categorical alignment and Lapse. – a simpler theory – distinct typological predictions 3

Categorical Alignment • Gradient alignment is massively nonlocal. – also not finite state (Eisner, Bíró) • Alignment has been used both gradiently and categorically. • All OT constraints should be categorical (McCarthy) . • Produces a better stress typology. 7

Previous Nongradient Work • Eisner (1998) – “Primitive Optimality Theory” – strictly local constraints • Kager (2001) – emphasis on rhythmic constraints • McCarthy (2003) – all constraints are categorical 8

Rhythmic wellformedness • Categorical alignment of one foot at the left or right edge. • Generate location of other feet from local properties of lapse and clash. • Lapses are preferred in certain positions. – adjacent to main stress – at right edge of domain 9

Constraints on Lapses *L APSE No two adjacent unstressed syllables. *I NITIAL -L APSE No lapse at the left edge. L APSE - AT -P EAK Lapse must be adjacent to the peak. L APSE - AT -E ND Lapse must be adjacent to the right edge. 10

Local *L APSE Kager (2001): No two adjacent unstressed syllables. (I.e. *00) McCarthy (2003): * σ̆ / σ̆ 16

Nonlocal *I NITIAL- L APSE Kager (2001): No lapse at the left edge. (I.e. *00 / [ ) McCarthy (2003): * σ̆ / Wd [ σ̆ 17

Replacing *I NITIAL- L APSE Rule out: [ σ̆ ( σ̆ Nonlocal lapse avoidance: * σ̆ / Wd [ σ̆ Local foot alignment (categorical): Align-L (Wd, Ft) 18

Di ff erences from *I NITIAL- L APSE • Same basic force in an iambic system. – 0(01) violates both equally – if unary 0(1) then only Align-L is violated – issue then becomes syllable weight • Potential di ff erence in a trochaic system. – 0(10) violates Align-L but has no lapse – increases number of violations, but no e ff ect to typology (as we’ll see) 19

Nonlocal L APSE-AT- E ND Kager (2001): Lapse must be adjacent to the right edge. (I.e. If 00 then 00] ) McCarthy (2003): * σ̆ / σ̆ α where α is non-null 20

Replacing L APSE-AT- E ND Rule out: σ̆ ) σ̆ unless ] Wd Nonlocal lapse avoidance: * σ̆ / σ̆ α Local foot non-alignment: *Align-R (Word, Foot) 21

Di ff erences from L APSE-AT- E ND • Pushes foot from right edge. – lapse there rather than ealier in word – equal to extrametricality • Similar e ff ect for a trochaic system. – (10)0 satisfies both equally – if unary (1)0 then only Align is violated – issue is again syllable weight • Potential di ff erence in an iambic system. – (01)0 satisfies *Align-R and has no lapse – could change violations elsewhere in word 22

Nonlocal L APSE-AT- P EAK Kager (2001): Lapse must be adjacent to the peak. (I.e. If 00 then 100 or 001) McCarthy (2003): * σ̆ / α σ̆ β where α does not end and β does not begin with σ́ 23

Replacing L APSE-AT- P EAK Rule out: σ̆ ) σ̆ ( σ̀ , σ̆ ( σ̆σ̀ ) , etc. Nonlocal lapse avoidance: * σ̆ / α σ̆ β where α or β ≠ σ́ Local foot non-alignment: *Align (Hd(Wd), R; Ft, L) or L, R 24

Di ff erences from L APSE-AT- P EAK • Symmetry not built into *Align constraint, but not needed anyway. – main stress foot is at left or right edge, so only the other side can abut a foot – potentially distinct if foot extrametricality • Conceptually, a kind of clash avoidance. – foot pushed away from main stress – prevents the unfooted syllable — and the lapse — from bein ɡ in other positions 25

Extrametricality • Preference for final lapse is the expression of final extrametricality. – Kager’s L APSE-AT- E ND – Local *A LIGN -R • Many typologies assume that initial extrametricality is impossible. • It’s rare, but not impossible. – Symmetrical *A LIGN -L 34
